My dear college roommate has asked me to bake a cake for her engagement party. She provided the recipe she would like, and I'm going to do a test run this week to make sure she actually likes it before the day of.

Here's the question: the recipe calls for 3 pans, and I only have one. I have none of the technical knowledge of baking to know if I can pull this off with just one pan, baking each layer one at a time. Will the batter do something funky in the wait time? Will the pan have to cool completely between layers? Should I just bite the bullet and buy two more pans because I love my friend and this is what she asked me to make? Help me, hivemind, you're my only hope!
